[RFC PATCH 00/34] msm: msm8660 and msm8960 clock support

[RFC PATCH 00/34] msm: msm8660 and msm8960 clock support

[David Brown]

The MSM8660 and MSM8960 have had out-of-tree clock drivers for quite
some time.  Since people can now order the Dragonboard with the
MSM8660, I thought it would be good to make sure these get sent out.
Saravana is actively working on this getting this code into the tree,
so this RFC is mostly to make the code available for people who get
the hardware before this work is done.

I'll also put these changes on top of a recent version of Linus'
master branch and make them available at

  git://codeaurora.org/quic/kernel/davidb/linux-msm.git msm-clock-rfc

[RFC PATCH 34/34] msm_serial: fix clock rate on DMA-based uarts

[David Brown]

The driver explicitly requests a clock rate for the UART, but it is
off by a factor of four from the dividers that it programs into the
UART.  Fix this by setting the rate to 1/4 of the current value.
